Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

Adsorption isotherms for water vapor on powdered cesium iodide are reported. Both macroscopic and microscopic (single-particle) samples of CsI powder from the same source were studied by two different techniques. The adsorption isotherms for the macroscopic samples were obtained using a Cahn 2000 Electrobalance, which leaves the sample uncharged during the measurement and utilizes a conventional microbalance to measure the relevant mass changes. The adsorption isotherms for the microscopic samples were obtained using a custom-made two-ring electrodynamic balance to measure the mass changes due to adsorption that occurred for single suspended charged particles of the CsI powder. Here, the relevant mass changes were determined from the changes observed in the required particle suspension voltages in the balance. The total charge on each particle studied was determined using the electron stepping technique. Based on the classification scheme of Brunauer, Emmett, and Teller, it is concluded that type III adsorption isotherms were observed for both the macroscopic and the single-particle CsI samples, which would indicate a multilayer adsorption process. The isotherms for the macroscopic and the single-particle CsI samples, while exhibiting the same basic shape, were found to vary greatly in magnitude. It is believed that this variation in magnitude is primarily due to the charge on the microscopic samples interacting attractively with the highly polarized water molecules and thus significantly increasing the multilayer adsorption of water. Some possible chemisorption was also indicated for both the charged and uncharged CsI, as evidenced by an inability to completely regenerate either the macroscopic or the microscopic samples.
